Remington 22LR Thunder Bolt 5000rd case

They are a bit dirty and leading is a problem especially in barrels that haven't been broken in or aren't properly cleaned. Anyone who has run a bore brush through a .22lr knows how tight the tolerances tend to be, 5 min of your time after shooting with a little hoppes #9 and it'll be squeaky clean. I've never experienced an issue getting a cleaning rod through a barrel after shooting these. Me and my friend would take a couple thousand with us on an outing and we never come back with ammo. Never tried them through a bull barrel though. Aside from the leading these rounds are nowhere near as dirty as some others I've tried. They have shown great accuracy out of the large variety of .22 rifles I've shot them through. Above all they are inexpensive, anyone who volume shoots there .22's will appreciate these rounds. If you are just shooting at targets I say buy bulk and shoot lots.

Don't Shoot too Many at One Outing,
November 16, 2010

Bought a bunch of these. Used a couple of hundred one afternoon in my mark II bull barrel. The barrel got so leaded up that I could not get a cleaning rod through. Had to have a gunsmith fix it. I would only get these if you are only going to fire a few at a time and clean the gun. Otherwise, I would recommend going with Federal or Remington copper jacketed. I have shot hundreds of the copper jackets at one outing with no problem.
